Patent CA-2322799-A1 (CA)
Title: Microscope slide system and method of use
Inventor: RICHARDSON TIMOTHY M
IPC: B01L3/00
Filed: 1998-03-20
Abstract: A slide system allowing rapid, sterile, clean and safe preparation and use of microscope slides containing sample materials including living and/or hazardous preparations or samples. In one embodiment, the system comprises a slide base and cover slip which are preferably precleaned and supplied in a sterile wrapper. The cover slip, slide base or both have an adhesive coating that surrounds a sample area to adhere the cover slip to the slide base, thereby creating a sealed sample area or chamber that is defined by the slide, the cover slip, and the adhesive. In another embodiment, the slide base has one or two grooves or depressions in the surface of the slide base positioned within the sample area, the grooves or depressions accommodating extra or expanding sample material to prevent loss of the sample material into the environment and prevent damage to the adhesive and/or cover slip. A layer of an active element, such as a neutralizing compound, can be provided to neutralize sample materials before they escape past the adhesive. The wrapper is designed to facilitate easy handling and to permit convenient and easy mounting of sample material into the slide.
